Description

The in_wch() and win_wch() functions retrieve the complex character and its rendition
located at the current cursor position of the stdscr window and
window win, respectively. The mvin_wch() and mvwin_wch() functions retrieve the complex character
and its rendition located at the position indicated by the x
(column) and y (row) parameters (the former in the stdscr window; the
latter in window win).

All these functions store the retrieved character and its rendition in the
object pointed to by wcval.
